Left Ventricular Assist Device
Booster pump implanted in the abdomen with a tube inserted into the left ventricle. An LVAD is a "bridge to transplant" or destination therapy when heart transplantation is impossible.
NOT pulsatile, just a continuous flow. Will not feel a pulse.
Inflow cannula - in the LV blood flows into it.
Pump - in the abdomen
Drive line - connected to the pump out to the external battery pack.
Outflow cannula: enters the aorta and brings the blood out to the body
-Low Von Willinbrands factor.
-Coagulopathic due to foreign body.
Bridge to transplant
LVAD INR goal
Unresponsive LVAD pt
NO CPR!! Could tear the device out of the patient's heart.
Auscultate and listen for a hum. If no hum, need to troubleshoot the VAD.
If there is a hum, they are unresponsive for other reasons.
Intra-aortic balloon pump
Pneumatic pump that provides counter pulsation offloading the LV. Is a retrograde catheter inserted into the descending aorta via the femoral artery.
It inflates in diastole and deflates in systole.
This increases coronary blood flow and DBP during diastole.
It decreases after load and SBP during systole.
Keeps the MAP the same!!
Centrifugal pump. Has an inflow catheter to the RA via the FV, and an outflow catheter into the descending aorta via the FA. Full CO support.
-Supports heart and lungs
-outflow catheter takes blood from patient
-Blood goes through an oxygenator and external VAD
-Inflow catheter takes blood back to patient
-Provides full support: cardiac output and doing the job of the lungs.
-Bypass at the bedside
-Blood exits the venous side and is oxygenated and then returned to the venous side too.
-Only supports the lungs
Sets a tidal volume.
By setting a tidal volume and a respiratory rate, you know the minute ventilation.
Beneficial for achieving a specific PaCO2.
Can result in high peak pressures if compliance decreases. Can also cause dysyncrony.
Sets a pressure in order to achieve a desired tidal volume.
TV can be unstable with a change in compliance and resistance.
A minimum number of preset mandatory breaths are delivered by the ventilator, but the patient can also trigger assisted breaths.
The patient makes an effort to breath and the ventilator assists in delivering the breath.
The breaths are not spontaneous. They are patient triggered, but the breaths are still delivered by the ventilator.
Provides full support. Keeps work of breathing requirement low.
Complication: Hyperventilation resulting in respiratory alkalosis.
Synchronous Intermittent Mandatory Ventilation (SIMV)
The ventilator delivers a preset number of mandatory breaths, but also allows the patient to trigger additional breaths in between mandatory breaths. Can set a controlled pressure or a controlled volume.
Partial ventilatory support. Patient can contribute to some of their minute ventilation. Helps wean off the ventilator. Reduces V/Q mismatching.

Cranial Nerve Mnemonic
Reduction in body temperature to 32-34C within hours after cardiac arrest to decrease the risk of neurological injury.
Decrease metabolism and demand for oxygen.
Indications for Therapeutic Hypothermia
Not following commands or having purposeful movements after arrects
Contraindications for Therapeutic Hypothermia
Active uncontrolled bleeding
